The research is aimed at expanding the technological capabilities of electrical processing methods through the use of programming systems for the technical characteristics of electrode tools (EI) directly in a digital model with their subsequent production by additive methods. The article discusses the issues of obtaining parts of complex shape. This is realized by the method of preliminary 3D printing of the electrode-tool with subsequent metallization of the working surfaces, which excludes finishing with the use of expensive equipment. However, the process of designing such a tool is associated with the complexity of its implementation for the conditions of a single or pilot production. The approach proposed by the authors to the design and manufacture of a complex-shaped combined EI makes it possible to significantly reduce its cost, especially at the stage of debugging the technological process in the conditions of launching the product into production.
